In my case both TL and outhaul are internal, so if the TL is changed to the gooseneck center sheave, the outhaul could just exit where the TL formerly did.
Kind of a puzzle with an external topping lift. Could you add a cheek block near the gooseneck and keep the TL external? Would that create an undesirable twist when led down and back? Boats used to have a sheave at masthead for the topping lift, which gave easy control. You could always put a sheave there and lead the TL down the mast and back.
Or, you could continue to enjoy climbing on the cabin house to adjust the topping lift. That's what I currently do. It is a reason to get out of the cockpit and look around and feel like a right jolly sailor lad. Frankly, with everything led back to the cockpit, even on a 38, it can get pretty crowded there.
